Regarding the feed temperature of the distillation tower
Thread Content
I would like to ask what the relationship is between the feed temperature of a distillation tower and the bottom temperature of the tower. If there are changes or fluctuations in the feed temperature, can these be compensated for by adjusting the bottom temperature, thereby mitigating the impact of such changes on product quality?
Changes or fluctuations in the feed temperature can be compensated for the impact they have on product quality by adjusting the bottom temperature of the tower; however, this will disrupt the balance of the entire system. It is necessary to identify the root cause and stabilize the feed temperature.
What is the feed temperature? How is the temperature at the bottom of the tower controlled?
The feed temperature of the tower determines its feed position, and fluctuations in feed temperature can affect the products at the top and bottom of the tower. Generally, the feed temperature is selected at the bubble point.
Feed temperature, the amount of vaporization of the oil at the bottom of the tower, the properties of the feed oil, and tower pressure are all factors that affect the bottom temperature of the tower. Feed temperature can influence the bottom temperature, but the bottom temperature cannot determine the feed temperature; it is the distillation heater that determines the feed temperature.
